  30 - compatible : Should be
  31     "dlg,da9062" for DA9062
  32     "dlg,da9061" for DA9061
  33 - reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
  34   modified to match the chip's OTP settings).
  35 - interrupts : IRQ line information.
  36 - interrupt-controller
  37
  38 See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt for
  39 further information on IRQ bindings.

  41 Sub-nodes:
  42
  43 - regulators : This node defines the settings for the LDOs and BUCKs.
  44   The DA9062 regulators are bound using their names listed below:
  45
  46     buck1    : BUCK_1
  47     buck2    : BUCK_2
  48     buck3    : BUCK_3
  49     buck4    : BUCK_4

  51     ldo2     : LDO_2
  52     ldo3     : LDO_3
  53     ldo4     : LDO_4
  54
  55   The DA9061 regulators are bound using their names listed below:
  56
  57     buck1    : BUCK_1
  58     buck2    : BUCK_2
  59     buck3    : BUCK_3

  68
  69 - rtc : This node defines settings required for the Real-Time Clock associated
  70   with the DA9062. There are currently no entries in this binding, however
  71   compatible = "dlg,da9062-rtc" should be added if a node is created.
